Comparison of external growth measurements^* reveals no difference between F₁ transgenic frogs and wild-type frogs. Individual values indicate the mean measurement for each group ± standard deviation

Individual genetic background	IOD	LCD	SVL	HL1	HL2	FL	W
Wild type (n = 8)	4.48±0.32	7.33±0.46	24.36±2.94	26.67±2.63	32.46±3.66	12.13±1.01	1.74±0.70
ROSA26:GFP (n = 8)	4.82±0.39	7.77±0.57	24.67±3.73	29.22±4.11	34.61±5.23	12.46±1.64	1.81±0.95

^*IOD, interocular distance; LCD, lateral cranial distance; SVL, snout–vent length; HL1, hind limb length, measured from the longest toe to the hip when the limb is extended 90° from the long axis of the body; HL2, hind limb length, measured from the longest toe to the vent when the limb is extended 90° from the long axis of the body; FL, forelimb length; W, weight. Linear measurements are expressed in millimeters; weight is expressed in grams.
